You mean Intel's 0day robot?
I believe that thing has by now enough logic to figure out which branch
to base patches ontop. Or maybe there's some magic incantation to tell
it which base c

Simplify tpm_read_log_of() by moving reusable parts of the code into
an inline function that makes it commonly available so it can be
used also for kexec support. Call the new of_tpm_get_sml_parameters()
function from the TPM Open Firmware driver.

Presently ima_get_kexec_buffer() doesn't check if the previous kernel's
ima-kexec-buffer lies outside the addressable memory range. This can result
in a kernel panic if the new kernel is booted with 'mem=X' arg and the
ima-kexec-buffer was allocated beyond that range by the pre

RISC-V recently added kexec_file() support, which uses enables kexec
IMA. We're the first 32-bit platform to support this, so we found a
build bug.

The memory area of the TPM measurement log is currently not properly
duplicated for carrying it across kexec when an Open Firmware

The of-tree subsystem does not currently preserve the IBM vTPM 1.2 and

subsystem may verify the IMA signature of the kernel and initramfs, and
measure it. The command line parameters passed to the kernel in the

Some recently added selftests don't have their binaries in .gitignores,
so add them.
I also alphabetically sorted sampling_tests/.gitignore while I was in
